The owner gave his car willingly to the dealer, he would have needed to furnish this information that he has a video recording device set up in the car OR should have turned it off. Its similar to having a 'nanny' cam in your home -- but home vs. car debate wouldn't be the same deal.

If the guy stole his vehicle it would have been a different with the video. As with anything in the law -- grey areas all around.

Not video recording, sound recording. What about my example of the Progressive good driving dash cam? Scroll up in the thread and read it.
